I. Core Function: Comprehensive Coverage from Safety to Performance
Enhancing Safety Systems: Silicones play a key role in automotive safety. For example, airbag coatings enhance the airtightness and high-temperature resistance of the fabric, ensuring reliable deployment under high temperatures and high pressures during a collision. Regarding battery safety, silicone thermally conductive encapsulants are used for sealing and bonding power battery packs. They combine waterproofing, insulation, thermal conductivity, and fire resistance, providing multiple layers of protection for new energy vehicle batteries.
Upgrading Thermal Management: As the power density of new energy vehicle electric drive systems increases, thermal management becomes a technical bottleneck. Silicone thermally conductive materials optimize thermal conduction paths to efficiently transfer heat from motors and electronic control modules to the cooling system, ensuring stable operation across a wide temperature range of -40°C to 200°C. For example, a thermally conductive silicone grease developed by one company can improve the heat dissipation efficiency of IGBT modules by 30%, helping electric drive systems achieve 97.5% energy efficiency. Breakthroughs in Lightweighting and Durability: Silicone elastomers contribute to automotive lightweighting through their triple functions of shock absorption, sound insulation, and sealing. Their high-temperature resistance surpasses that of traditional rubber, enabling long-term use in high-temperature areas such as the engine compartment and exhaust system. Their chemical resistance also makes them ideal sealing materials for fuel and hydraulic systems. The use of silicone shock absorbers in one vehicle model reduced vehicle weight by 15% and improved NVH performance by 20%.

II. Technological Frontiers: The Innovation Engine of Intelligence and Electrification
Smart Cockpit Innovation: Silicone leather, with its skin-friendly feel and wear and dirt resistance, is reshaping interior standards. LuxSense™ silicone leather, the world's first approved for vehicle seats, reduces carbon emissions by 60% compared to genuine leather and features high-temperature self-healing properties, meeting the comfort requirements of the "third living space" in Level 3 autonomous driving.
Advanced Intelligent Driving Support: In response to the trend toward miniaturization and integration of ADAS sensors, silicones provide integrated solutions for electromagnetic shielding, environmental protection, and heat dissipation. For example, a company developed an EMI conductive adhesive that shields high-frequency interference above 10 GHz, ensuring stable operation of LiDAR in complex electromagnetic environments. A thermal interface material with a thermal conductivity of 12 W/m·K meets the stringent heat dissipation requirements of high-performance chips.
Sustainable technology is being implemented: Silicone self-healing tires use an internal sealing layer to instantly repair punctures, eliminating the need for spare tires and reducing the weight of each vehicle by over 50 kg. This material has a recyclability rate of over 90%, and when combined with carbon nanotubes, the resulting thermal interface material improves the heat dissipation efficiency of motor controllers by 40%, promoting the low-carbonization of new energy vehicles throughout their entire life cycle.
